In one example, a method includes: receiving a first input value associated with a first data field; responsive to determining the first data field is associated with a delta operation, selecting a second input value associated with a corresponding second data field of a previously transmitted message; comparing the first input and second input values to determine if the first and second input values are equivalent; when the first and second input values are not equivalent, generating a message, wherein the first data field includes only data of the first input value not included in data of the second input value, and providing an operator symbol indicating the delta operation to specify that the first data field of the message includes only data of the first input value that is not included in data of the second input value associated with the second data field of the previously transmitted message. |

1. A method comprising:
receiving, by a computing device, an input value for a data field associated with a compression technique; and responsive to determining that data of the input value is equivalent to data in a previously transmitted message, applying the compression technique by the computing device, without user intervention, to generate a message that does not include the data of the input value, including:
receiving, by the computing device, a first data field identifier that identifies the data field,determining, by the computing device, a lookup operation, wherein the lookup operation selects a second data field identifier stored in a field operator cache, wherein the second data field identifier matches the first data field identifier, and wherein the second data field identifier is associated with an operator identifier that indicates a delta operation,in response to selecting the second data field identifier, selecting, by the computing device, the operator identifier, anddetermining, by the computing device, that the operator identifier indicates the delta operation. |
